• Product Code: Alpha 275 3D neon
  • Availability: Pre-Order


High buoyancy and strong rotation effect packaged in a low profile are the most distinctive features and the ideal protection in combination with heavy-weather clothing. Signal-colored cover with reflective strips for for enhanced visibility.

Because own buoyancy and air pockets in heavy weather clothing or protective suits to counteract the rotational forces of buoyancy of life jackets, the three-dimensional design of the buoancy chamber is designed with a large volume before the chest area. This is enhanced by the rotating action of the lever principle. About 20 centimeters higher protruding from the water the lifejacket/lifevest is much more visible, especially with mounted emergency light. 

Nevertheless, the weight is light and the mobility high. Thus, this model is proved in different industrial areas and standard in many Waterways and Shipping Offices. The lifejacket/lifevest is also suitable for light clothing and ideal for everyday use. 

Compared to conventional buoyancy chambers the buoy of the Alpha 275 3D is cut that after inflating two additional triangular air bags, which rise substantially perpendicular from the center of the lifejacket/lifevest wearers chest. 

They extend into the air - in the "third dimension", that's why we call it 3D.

  • Approved acc. to DIN EN ISO 12402-2 (CE-Sign) 
  • also available as ALPHA 275 3D in blue (Art.-Nr. 12449).

Lifejackets need a service too

Where the safety of peoples’ lives is concerned, regular inspection of the equipment concerned is absolutely essential. This also applies to lifejackets. Natural aging process can influence the properties of the material and also the functioning of the automatic inflator system is not immune to possible damage (among other things operational errors). In other words: the life of a lifejacket must be limited. The corresponding time frame has been set at 10 years, a decision borne authoritatively by the members of the German Association for Sea Rescue Equipment (FSR), and which complies with the law of safety and product liability.

A prerequisite for this lifetime is an inspection of the lifejacket by an authorized servicing station or the manufacturer at least every two years.

Safety as a visible sign

Regular inspection is documented by the FSR-Service-Sticker, which, similarly to a car’s MOT sticker, signalizes the month and year of the next service due.


The regular system check by the expert comprises testing the buoyancy chamber for air leaks as well as a scrutinizing check of the fully automatic inflation system. Moreover, within the framework of this SERVICE we can offer:

  • Repair
    Removal of any defects discovered in the course of the inspection as well as replacement of the complete protective cover or buoyancy chamber.
  • Conversion / Optional extras
    Converting from manual release to automatic inflation, adding a spray hood, installation of an emergency light and further signalling accessories.

Receipt of the new FSR-Service-Sticker confirms, so to speak, the correct functioning of the rescue equipment and always reminds you of the Date of the next inspection, the sticker being clearly visible from the outside.
